Hello everyone
I have variables. And I want to analyse the variables using a function to get the Hotelling ttest for each point.for
x y z
0.1 0.2 0.3
0.4 0.6 0.1
0.8 0.7 0.4
0.6 0.5 0.4
0.5 0.5 0.5
0.2 0.4 0.8
0.4 0.8 0.9
0.4 0.5 0.3
How do I implement a window size of 2 which will always be in even numbers and a shift of 1 for the variables
For instance if I use a window size of 2 using one shift
x y z
0.1 0.2 0.3
0.4 0.6 0.1
The next window size is
x y z
0.4 0.6 0.1
0.8 0.7 0.4
Then group the window sizes into
group x y z
1 0.1 0.2 0.3
1 0.4 0.6 0.1
2 0.4 0.6 0.1
2 0.8 0.7 0.4
I can then analyse it using the function
[e] = T2Hot2ihe(Bix, 0.05); to give me first result. Please note that the results must be equal to the length of variables
it continues to the next window size.
x y z
0.4 0.6 0.1
0.8 0.7 0.4
The next window size is
x y z
0.8 0.7 0.4
0.6 0.5 0.4
Then group the window sizes into
group x y z
1 0.4 0.6 0.1
1 0.8 0.7 0.4
2 0.8 0.7 0.4
2 0.6 0.5 0.4
This goes down until there is no more window size.
can then analyse it using the function
[e] = T2Hot2ihe(Bix, 0.05); to give me second result.
Please note that the result is obtain for point and ends at the last point where there is no window size to compute.
I would be very grateful if you help me with this
Thanks
Jo
